I’m just back from IBEX 2013. The vendors joke was that I was the only person there who wasn’t a vendor nor speaker.  (still cranky about that.  They so rejected my paper on putting QR codes in design prints.  I thought it was great and the future.)  Attendance was way down it seemed.  I saw very few people that I knew.  Next year will be Tampa so maybe that will help.
The big test for me is if I come back with new, useful information that I did not have before. I did. I will post in the coming days.
One big change was that cameras were allowed of the exhibits. I took a lot of pics of cool stuff and will post.
The seminars ranged from very useful (secondary bonding) to the bizarre (design of a yacht by an artist with Frank Gehry).  Actually a Gehry yacht is kind of like an Americas Cup boat, in just one way.  Billionaires showing that they have more money than God and can do things that you could not dream of.  Most boats read efficiency just by the design elements, like curved corners.  The Gehry boat telegraphed that it had no interest in efficiency.  I will find a pic of that.  5 years spent just designing windows and cockpit.

So, back and lots of good stuff coming.  Meanwhile I have to catch up on work here today.
